Application filed August 1, 1904. Serial No. 219,071.

To all whom it may concern:

Be it known that I, JULIUS L. KLEMME, a citizen of the United States,residing at Quincy, in the county of Adams and State of Illinois, haveinvented new and useful Improvements in Heaters, of which the followingis a specification.

This invention relates to improvements in heating stoves constructedespecially for burning bituminous coal; and its object is to provide fora perfect combustion of the fuel to thereby secure the maximum degree ofheat without the accumulation of soot and with a material saving in thequantity of fuel consumed.

A further object of the invention is to provide a double heater whichcan be utilized to heat the room in which the heater is located and alsoanother room.

In the accompanying drawings, illustrating an embodiment of theinvention, Figure 1 is a vertical sectional view of the heater. Figs. 2and 3 are horizontal sectional views on the lines 2 2 and 3 3 of Fig. 1.Fig. 4 is a detail sectional view on the line 4 4 of Fig.2.

In the drawings, 5 is a fire-box, 6 the ashpot, and 7 theheating-chamber of the heater, the general construction of these parts,as well as the shape and proportions of the whole heater, being capableof more or less variation without departing from the invention. In thedome 8 above the heatingchamber I provide an annular air-receivingchamber 9, which communicates with a ventiduct 10, connecting with ahollow airdistributing ring 11 between the fire-box and theheating-chamber. Air enters the airchamber 9 through a damper 12 at thefront thereof and passes through the ventiduct and escapes throughopenings 13 in the distributing-ring. This air is heated to a hightemperature in the air-chamber and ventiduct between the time it entersthe air-chamber and is discharged from the distributing ring, and itfurnishes a fresh and sufficient supply of oxygen to thecombustion-chamber 14 within the distributing-ring and between thefire-box and heating-chamber to provide a perfect combustion of the fueland entirely consume all the soot which ordinarily passes off. Thevolume of air can be regulated by adjusting the damper, which may be ofany suitable construction. I prefer to make the distributing-ring ofangular form in cross-section, with an upwardly and inwardly inclinedinner wall 11, as shown, so

that the air dischar ed therefrom will be directed to a more or lessextent downwardly; but this ring may be otherwise shaped, if desired. Atthe top of the dome I provide an opening 15, to which the stovepipe isconnected in the usual manner, and a grate 16 is located at the bottomof the fire-box. I also provide a hot-air chamber 16, preferably at theback of the drum 17 of the heater and behind the air-passage 10, andthis chamber communicates at the bottom with a cold-air chamber 18,which extends down beside the fire-box and the ash-pot and is providedwith an opening 19 at the bottom. The cold air entering the chamber 18through the opening 19 and passing up into the chamber 16 will becomehighly heated by the time it reaches the top of the chamber 16, which isprovided with a collared opening 20 to receive a fluepipe by which theheated airis carried to another room than that in which the heater islocated. If it is not desired to utilize this double heater formed bythe chambers 18 and 16, the opening 20 may be closed.

It is not necessary to enter into the other details of construction ofthe heater, because they may be changed in many respects withoutdeparting from the invention, which consists, essentially, in taking theair-draft into the front of the chamber 9 and discharging it after it isheated to a high temperature into the combustion-chamber and providingalso the double heater at side of drum.

A heater constructed in accordance with my invention will provide acommerciallyperfect combustion of the fuel and prevent accumulation ofunconsumed fuel in the heater and stovepipe. By reason of this perfectcombustion a greater volume of heat is obtained from a given amount offuel, and consequently in the ordinary use of a heater considerably lessfuel is required to obtain the desired amount of heat. The air-chamber9and the ventiduct 1O constitute, in effect, a continuous passage fromthe air-draft from the top front of the heater to the distributingring,and in this passage the air is heated to a' high temperature.

Without limiting myself to the exact construction and arrangement ofparts herewith shown and described, what I claim, and desire to secureby Letters Patent, is

1. 'In a heater of the character described, the combination of a drum, acombustionchamber, a heating-chamber above the combustion-chamber, adome above the heating chamber, an annular air-receiving chamber locatedin the dome adjacent to its outer wall and having its inlet-opening atthe front 01' the heater, an air-distributing ring in thecombustionchamber, a vertical ventiduct within the heating chamber atthe back thereof and connecting the receiving-chamber and thedistributing-ring, and a hot-air chamber outside of the drum behind theventiduct, a part of the drum forming a wall for both the hot-airchamber and the ventiduct.

2. In a heater of the character described, the combination of a drum, acombustionchamber, a heating-chamber above the combustion-chamber, adome, an annular air-receiv ng chamber located in the dome adjacent toits outer wall and having its inlet- I opening at the front of theheater, a hollow air-distributing ring in the combustion-chamher andhaving an inwardly and upwardly inclined wall provided with openingsthrough which the air is discharged downwardly in thecombustion-chamber, a vertical ventiduct within the heating-chamber atthe back thereof and connected at one end to the back of thereceiving-chamber and at its other end to the back of thedistributing-ring, and a hot-air chamber outside of the drum, a part ofthe drum forming a wall for both the hotair chamber and the ventiduct,
